One Marathon a Month in 2009??

Wow, I just had a crazy idea... but depending on how I do in Honolulu and what my time comes out to be... I might consider running 1 marathon a month in 2009. If I feel the way I did on my 20 mile run, then I should not have a problem. My 20 miler went great 2 weeks ago and felt no soreness or pain whatsoever. In fact I did in under 3 hours. If I feel great, I actually might go for it, which will change my plans for training for a tri. There is so much I want to do as far as the physical aspect. If I am able to run 1 marathon a month next year, then I am going to attempt to run an ultra in 2010 or maybe by the end of 2009. Meaning I would run either a 50 mile or 100 mile race.
Note: The # is the marathon number I have done, so by the end of 2009, I would have ran 23 marathon in 5 years in total.

Here is my tentative schedule for 2009
